6.3 Auxiliary input configuration
Fig.6.4
InsulGard accepts three additional signals for PD correlation to a dynamics. One signal is always a
temperature. See the following paragraph for temperature channel configuration and calibration.
Two another inputs are configurable for Load Current or Humidity (J4) and for System Voltage or
Humidity (J5).
Most common configuration is Current and Humidity. The jumper position is shown in the figure 6.4. J4
configures Current channel for Current and J5 configures Voltage channel for Humidity.
Pre-Revision 1:
J6 in the shown position sets Current channel input impedance to 100 Ohms. Removing
the jumper will change the impedance to 1 kOhm. In
Revision 1
the current channel input impedance is
always 100 Ohms.
